Title:
METHOD FOR MEASURING MECHANICAL ERROR OF ROTATING TABLE AND METHOD FOR MACHINING PERIPHERAL EDGE OF PLATE
Document Type and Number:
Japanese Patent JP2015223683
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for measuring a rotation angle error (angle runout) and a rotation center error (center runout) with the rotation of a rotating table by using a measuring substrate capable of being simply made, and to provide a method for machining a peripheral edge of a plate and containing the above method.SOLUTION: A measuring substrate displaying a circular mark on a virtual circle centering on a point to serve as a rotation center when carried in a rotating table of a machining machine is fixed on the table intended to measure an error of a rotation angle, the circular mark is read by using a camera being set in a fixed position every time the table rotates by a predetermined angle, carrying-in error of the measuring substrate to the table top is detected from the position of the mark that is read, and the angle runout and center runout of the table are detected from the position of the mark after being corrected by the detected carrying-in error. As the measuring substrate, the substrate displaying multiple circle marks at a predetermined equally divided angle on the virtual circle and the substrate displaying one mark on the virtual circle can be used.
